[The helminth fauna of the red fox (Vulpes vulpes LINNE 1758) in the administrative district of Karlsruhe. 1. Cestodes].

Between February 1989 and January 1990 a total of 801 red foxes were examined for the presence of cestodes. Echinococcus multilocularis could be noted with an infection rate of 11.6% in the small intestine of the red fox. The following other cestodes were found (in order of frequency) Taenia crassiceps (19.9%), Mesocestoides spp. (16.6%), Taenia polyacantha (7.0%), Hydatigena taeniaeformis (0.7%), Dipylidium caninum (0.5%) and Diphyllobothrium latum (0.5%). Infections with Echinococcus multilocularis very often showed worm numbers between 11 and 100 specimen per fox. The number of worms of the other cestodes mostly varied between one and ten specimen per animal.
